An eager race of space colonists have settled too close to the home world of the Saucer Men. The Saucer Men use their knowledge of classic video games to mount an attack on the poor colonists.
The colonists armed with only their trusty missile launcher must defend against; ever multiplying asteroids, abducting saucers and shielded bombs!
Destroying the attackers has its advantage however. After each round of destruction the colonist have the chance to spend their success on advance rocket technologies or improve their colonies in the face of doom.
The game is played over a series of increasingly challenging levels, starting off at a slow pace and ending in total chaos.
